Hydraulic system for surgical applications

Abstract

A surgical device includes a plurality of cameras integrated therein. The view of each of the plurality of cameras can be integrated together to provide a composite image. A surgical tool that includes an integrated camera may be used in conjunction with the surgical device. The image produced by the camera integrated with the surgical tool may be associated with the composite image generated by the plurality of cameras integrated in the surgical device. The position and orientation of the cameras and/or the surgical tool can be tracked, and the surgical tool can be rendered as transparent on the composite image. A surgical device may be powered by a hydraulic system, thereby reducing electromagnetic interference with tracking devices.

1 .- 40 . (canceled) 
     
     
         41 . A hydraulic drill comprising:
 a chuck configured to receive and support a rotary bit therein;   a turbine rotationally coupled with said chuck; and   a housing comprising an inlet fluid flow path connectable to an inlet conduit;   
       wherein said inlet fluid flow path is configured to direct fluid from the inlet conduit toward said turbine with sufficient flow velocity to rotate said turbine and hence said chuck and rotary bit. 
     
     
         42 . The hydraulic drill of  claim 41 , further comprising a hydrostatic bearing coupled with said turbine. 
     
     
         43 . The hydraulic drill of  claim 41 , further comprising an air bearing coupled with said turbine. 
     
     
         44 . They hydraulic drill of  claim 41 , further comprising a controller coupled to a flow valve in said inlet fluid flow path or inlet conduit, wherein said controller is configured to adjust the flow velocity against said turbine. 
     
     
         45 . The hydraulic drill of  claim 44 , further wherein said controller is supported by or within said housing. 
     
     
         46 . The hydraulic drill of  claim 41 , further comprising a flow meter configured to measure the flow velocity within said inlet fluid flow path. 
     
     
         47 . The hydraulic drill of  claim 41 , wherein said housing further comprises an outlet fluid flow path connectable to an outlet conduit. 
     
     
         48 . The hydraulic drill of  claim 47 , wherein said outlet fluid flow path has a same cross-sectional size as compared to said inlet fluid flow path. 
     
     
         49 . The hydraulic drill of  claim 47 , wherein said outlet fluid flow path has a larger cross-sectional size as compared to said inlet fluid flow path. 
     
     
         50 . The hydraulic drill of  claim 47 , wherein said housing further comprises couplings configured to removably couple said inlet and outlet conduits with said housing. 
     
     
         51 . The hydraulic drill of  claim 41 , wherein said drill is configured to work with electromagnetic (EM) tracking. 
     
     
         52 . The hydraulic drill of  claim 41 , further comprising at least one camera. 
     
     
         53 . The hydraulic drill of  claim 52 , wherein said at least one camera is fixed in position rotationally. 
     
     
         54 . The hydraulic drill of  claim 52 , further comprising a tactile feature configured to provide a tactile indication of the orientation of said at least one camera. 
     
     
         55 . The hydraulic drill of  claim 54 , wherein said tactile feature is fixed in a rotational position on said housing.
